HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

5-Bromo-2,4-dimethoxypyrimidine serves as a key heterocyclic building block in medicinal chemistry and agrochemical synthesis. The electron-deficient pyrimidine core facilitates nucleophilic substitution, while the bromine at C5 enables efficient coupling reactions. The dimethoxy groups enhance solubility and direct regioselective functionalization under standard conditions.

Application

5-Bromo-2,4-dimethoxypyrimidine serves as a versatile building block in heterocyclic synthesis, enabling efficient access to pyrimidine-based scaffolds through palladium-catalyzed cross-coupling reactions. The bromine moiety provides high reactivity in Suzuki, Stille, and Negishi couplings, while the dimethoxy groups enhance solubility and offer orthogonal protection for downstream functionalization. This compound exhibits excellent bench stability and is readily purified by flash chromatography or recrystallization, making it ideal for use in medicinal chemistry and process development workflows.
